Engineering Machinery Components Glossary

• Piston Skirt: The lower cylindrical section of the Piston, designed to guide the piston in the Cylinder Liner. Caterpillar D8R Bulldozer 3406E Engine Piston Skirt.

• Main Bearing: Supports the engine's Crankshaft within the Cylinder Block. Cummins ISX15 Engine Main Bearing.

• Thrust Washer: Limits the axial (end-to-end) movement of the Crankshaft. Installed at the front or rear of the Crankshaft in the Cylinder Block. Komatsu PC200-8 SAA6D107E Engine Thrust Washer.

• Glow Plug: A heating device used to aid Diesel Engine starting in cold weather. Installed in the Cylinder Head. Kubota V3307 Engine Glow Plug.

• EGR Cooler: Cools exhaust gas before it is recirculated into the engine intake manifold. Located externally, attached to the Exhaust Manifold. Weichai WP12 Engine EGR Cooler.

• Connecting Rod Bushing: A bronze sleeve pressed into the small end of the Connecting Rod for the Piston Pin. Isuzu 4HK1 Engine Connecting Rod Bushing.

• Camshaft Follower: A component that rides on the lobes of the Camshaft to transmit motion to the Pushrods or directly to the Valves. Located within the Cylinder Block. Cummins QSB4.5 Engine Camshaft Follower.

• Oil Cooler Core: A heat exchanger that uses engine coolant to cool the lubricating oil. Typically mounted to the Cylinder Block near the oil filter. Caterpillar 320D Excavator C6.4 Engine Oil Cooler Core.

• Water Temperature Sensor: Monitors the temperature of the engine Coolant. Installed in the Cylinder Head or thermostat housing. Yanmar 4TNV98 Engine Water Temperature Sensor.

• Tappet: A component in the valve train that converts the rotating motion of the Camshaft into reciprocating motion. Located between the Camshaft and the Pushrod. Komatsu D61P-15 SAA6D107E Engine Tappet.

Expert Maintenance Corner: Engine Longevity Tips

Troubleshooting: Komatsu PC450-8 SAA6D125E Engine Overheating

Symptom: The engine temperature gauge consistently reads high, especially under heavy load. The engine may lose power. Fault Solution: A common cause, after checking coolant levels, is a failing Water Pump Assembly or a clogged Oil Cooler. Replace the Water Pump if you observe visible leaks or shaft play. If the coolant system is clean, inspect the Oil Cooler Core for internal sludge buildup which can block coolant flow and restrict oil cooling, leading to overall engine temperature spikes.

Essential Engineering Machinery Maintenance:

• Oil Analysis: Perform scheduled oil sampling (SOS) on all major systems (Engine, Transmission, Hydraulics) to detect premature wear, such as increased iron from Crankshaft Bearing wear or silicon from poor air filtration.

• Fuel System Inspection: Regularly inspect Diesel Pump pressure and test Injector spray patterns. Faulty fuel atomization leads to poor combustion and excessive carbon build-up, which can prematurely wear your Piston Rings.

• Air Intake Integrity: Ensure the air filter and all intake hoses leading to the Turbocharger are sealed tightly. Even small leaks can introduce contaminants that severely damage Cylinder Liners and Pistons.
